Description

Natural ecological stone road {friendly environmental fish way}

The present invention relates to a fishery, and more particularly to a natural ecological stone fishery that allows the fish to burn by continuously draining regardless of the change in water level.

Generally, all the facilities installed for the purpose of increasing the water level are generically referred to. The blowholes installed for the purpose of taking in the irrigation water have excellent workability and there are reinforced concrete blowers of the universal construction method. The riverbed maintenance hole, which is installed to alleviate the slope of the river and maintain the profile and cross-section, is divided into free fall hole and large hole. The free fall ball is the drop within 2m of the straight height, and the big drop is the free fall or very small, less than 50cm, and the facility that prevents the river bed from falling below the planned river bed is called the river bed retainer, and the reinforced concrete type with the same structure as the blow beam In addition, there are concrete blocks, stone sticking and stacking riverbed maintenance.

The stone attaching river bed is a method of evening the sandstone or concrete surface, and attaching the stone with a canine stone, crushed stone, amber stone, etc. In the case of sticking, the construction is carried out so that the joint is well-fitted, and in case of sticking There is a method of placing the stones side by side and filling them with a mortar between the joints, and the stone stacking river bed is a core with a stone or gravel as a core. Construction slope 1: 0.2 ~ 0.5 to stack stones on the surface The method is divided into racking and racking.

The stone pasting and stacking is a construction method for the purpose of the function using the stones scattered around the construction method according to the surrounding environment rather than the ecological environment of the river.

Natural river restoration methods include a fluid method made by stacking stones in multiple layers, and a cracking method for attaching stones using filters and concrete.

In Korea, the fluctuations in water level during the rainy season and during the rainy season are very large. In particular, in relatively large rivers, the stacked structures are often lost during the flooding, and in the case of the clay paste method using concrete and natural stone, the fish can not be linked due to fluctuations in the water level. There is a problem that can not play a role.

In view of this point, Patent No. 10621620 discloses a water level control type adobe device. The published fish apparatus includes an adobe body in which fish blocks are formed at regular intervals on the bottom layer; A door hinge hinged to the adobe body; A driving unit coupled to the door and the fixed shaft; And a support part installed at a downstream bottom of the adobe body to naturally slide the adobe body.

As described above, the drive unit for driving the gate door includes an inflow cylinder, and thus a separate device for manipulating the door is required.

And the Republic of Korea Patent No. 6712640 buoyancy automatic beam having an edo function is posted. The published automatic beam is a level control plate which is fixed to both sides integrally in a state seated on the top of the underwater beams are constructed across the river; A plurality of buoyancy tanks arranged at predetermined intervals along the longitudinal direction at the lower side of the water level control plate; A buoyancy body installed inside the buoyancy tank; A variable control rod coupled to the upper end of the vertical transfer rod installed in the buoyancy body and adjusting the overall height of the underwater beam while operating by lifting and lowering by buoyancy; The buoyancy tank has a configuration consisting of a buoyancy body operating means for selectively raising the buoyancy body by transferring the fluid pressure inside the pressure tank selectively.

In addition, Patent Registration No. 0714436 discloses a pillar-damping structure, and Patent Registration No. 1101899 discloses an esophageal system having an integrated ecological pathway of fish and benthic life.

Conventional fishes constructed as described above cannot form fish in response to changes in water level in floods and low water.

The present invention is to solve the above-mentioned problems, in conjunction with the fluctuations in the water level can form a passage for small fish, as the water level is lowered natural ecological stone sticking can lower the inclination angle of the small path of the fish Its purpose is to provide fishery.

Another object of the present invention is to provide a natural ecological stone door that can be opened and closed by buoyancy to the water gate corresponding to the water level as the water level is variable.

According to the present invention for solving the above technical problem, a natural ecological stone footpath is installed in a river or river, and a beam for confining water, and is installed in the beam, the first main small passage through which aquatic animals are injured during high water level With the first main fishbone to form,

It is installed on the side adjacent to the first main island and is stepped in accordance with the water level below the full water level, the aquatic animal is small and has a second main small passage connected to the first main small passage, and the second main small passage At least one second main door having a door unit for opening and closing the second main small passage by the water level in the beam on the inlet side of is characterized in that it is provided.

In the present invention, the inclination of the second main small passage is lower than the inclination of the first main small passage, and the natural stone on the surface of the first main and second main island to express the stacked state of natural stone Are attached.

The door unit is connected by a hinge shaft rotatably to the lower end side of the water gate to the beam or the second main island of the entrance of the second main small passage, and according to the change of the water level to generate buoyancy on the outer axis of the water gate. It is provided with a buoyancy generating member for opening and closing the water gate by adding or subtracting buoyancy.

The natural ecological stone island according to the present invention can form a passage through which the fish are small by interlocking with the water level, and when the water level is lowered, it is possible to form a small slope of the passage through which the fish are small, that is, the second main small passage. There is an easy way to injure aquatic animals. And since the natural stone is attached to the surface of the fish can create an environmentally friendly environment.

Figure 2 is a perspective view showing an extract of the natural ecological stone door door unit according to the present invention,
Figure 3 is a side view showing the operating state of the natural ecological stone paste according to the invention.

Natural ecological stone islands according to the present invention is nature-friendly and can form a passage through which the aquatic animals are small in association with the change in water level, an embodiment thereof is shown in Figures 1 to 3.

Referring to the drawings, the natural ecological stone island 10 according to the present invention is a beam 100 installed in a waterway, a river, a river or an estuary, and a first main island extending from the beam 100 to a lower side thereof ( 20). The first main island 20 forms a first main small passage 21 in which the aquatic animal is small in the full water level region of the water stored in the beam 100 and includes a first main body 22 through which water flows. The first main small passage 21 formed by the first main body 22 may have a gradient in which water flows smoothly so that the small phase of the aquatic animal can be made smoothly. However, the gradient of the first main small passage 21 may be adjusted in various ways depending on the conditions of the river or the flow rate, design conditions.

In addition, a plurality of second main islands 30 are installed at a side adjacent to the first main island 20 so as to be stepped according to the water level below the full water level region. The second main island 30 forms a second main body passage 31 which forms a second main small passage 31 through which the water can be discharged in a region below the water level discharged through the first main passage 21. 32). The second main small passage 31 forms a gradient in which water is discharged, and an end side of the second main small passage 31 is connected to the first main small passage 21. When a plurality of the second main doors 30 are provided, the second main small passages may be formed to be stepped with each other so that water may be discharged from different water level regions according to the change of the water level as described above. .

In addition, the second main airway 30 is provided with a door unit 40 for controlling the flow of water to the second main small passage 31. The door unit 40 is installed in the beam 100 or the first main body main body 32 to open and close the inlet of the second main small passage 31, and includes an opening and closing door 41, The opening and closing door 41 is provided with a buoyancy generating member 42 to be rotated by buoyancy. The opening and closing door 41 has a bracket 44 installed on the lower inner side surface of the second main door body 32 of the inlet side of the second main small passage 31 and the lower end side of the opening and closing door 41 of the hinge pin 45. The door is opened and closed by the buoyancy force of the water stored in the beam 100 so that the door opens and closes the inlet of the second main small passage 31. To this end, the buoyancy generating member 42 provided in the opening / closing door 41 is attached to the outer circumferential surface of the opening / closing door 41 to have a buoyancy generating space 42a for generating buoyancy. The buoyancy generating member 42 may be formed by forming a space on the inner circumferential surface of the second opening and closing door 41.

On the surfaces of the first and second main body bodies 22 and 32 and the surface of the beams, eco-friendly natural stones are attached to implement the environment of natural ecology. The natural stone is preferably attached so that the surfaces of the first and second main body bodies 22 and 32 are not exposed. Further, the first and second main small passages 21 and 31 may further include an inlet space or a velocity delay unit so that the small phase of the aquatic animal can be made smoothly. The flow rate support unit may be provided with protrusions that may delay the flow of water in the first and second main passages.

Natural ecological stone islands according to the present invention configured as described above can form a small flow path flowing water, that is, water that can be injured by aquatic animals irrespective of the water level and the dry season, and the water level between them.

In more detail, during the full water level, water upstream of the beam 100 flows to the downstream side through the first main small passage 21 of the main road 20. Accordingly, the aquatic animal on the downstream side may be injured from the downstream side of the beam to the upstream side of the beam using the first main small passage 21. At this time, since the second main small passage 31 of the second main island 30 is closed by the door unit 40, water does not flow. Since the buoyancy generating member 42 for opening and closing the door is installed in the opening / closing door 41 of the door unit 40, when the water level is relatively high, that is, when the opening / closing door 41 is submerged in water, Will remain closed.

When the water level is gradually lowered, the amount of water flowing through the first main small passage 21 of the first main airway 20 decreases, and the opening / closing door of the door unit 40 of the second main airway 30 decreases. The buoyancy acting on the 41 becomes small, and the open / close door 41 gradually opens. Therefore, the upstream water flows downstream through the second main small passage 31 and the first main small passage 21 of the second main door 30, and the aquatic animal on the downstream side of the beam has the first main small phase. It moves to an upstream side of the beam through the passage 21 and the second main small passage 31.

Particularly, since the outlet side of the second main small passage 31 of the second main door 30 is connected to the first main small passage 21, the gradient of the second main small passage 31 of the water is stored. We can make difference of water level not big. This may facilitate the movement of the aquatic animal through the first main passage and the second main passage.

The natural ecological stone island of the present invention is provided with a plurality of second main fish islands can form a continuous small passage as the water level is lowered as described above.

And when the water level of the water stored by the beam 100 is gradually increased, the opening and closing door 41 for opening and closing the second main small passage 31 of the second main road 30 to the buoyancy generating member 42 The buoyancy acting increases to close the opening and closing door 41, and water is discharged through the first main small channel 21 of the first main door 20 to form a small channel.

On the other hand, since the natural stone is attached to the surface of the beam 100 and the first and second fish bodies, it is possible to reduce the heterogeneity with the surrounding environment and to implement an eco-friendly fishery.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention.

Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.

The natural ecological stone island of the present invention is widely applicable to beams installed in various rivers, rivers, waterways, etc., and is applicable to facilities for discharging water in stages according to water levels.
